Abstract Maluku, Indonesia, has essential oil (EO) producing plants, namely eucalyptus ( Melaleuca leucadendron ), which are spread throughout the island. This study aims to determine the effect of geographical location on EO’s yield and chemical composition. The eucalyptus oil isolation method uses steam distillation and chemical composition analysis using gas chromatography–mass spectrometry. The results showed that the yield of EO from wilted leaf samples on Buru Island for point B1 = 1.35%; B2 = 1.19; B3 = 1.52; B4 = 1.88%; B5 = 2.13% and from Seram Island for point S1 = 0.71%; S2 = 1.02%; S3 = 0.78; S4 = 0.8%; and S5 = 1.01%. The yield of EO in the lowlands is higher on Buru Island in the lowlands (23.04 masl) and on Seram Island (46 masl). The levels of 1,8-cineole in EO for both island plains ranged from 26.89 to 47.32% and α-pinene levels between 3.84 and 43.45%. Minor compounds found on both islands are d -limonene, β-pinene, and cymene. There are minor compound components that are only found on each island. The geographical conditions of eucalyptus plants affect the quality and quantity of EOs. At higher locations, temperatures tend to be lower, which affects plant metabolism and produces less oil. The eucalyptus plantation area on Seram Island has high humidity, so the yield of EO is lower.
